Claims

[Claims for Utility Model Registration] l CDQ main body, high-temperature gas flow path with a primary dust collector, boiler with a deaerator for water supply, and low-temperature gas supply with a secondary dust collector In CDQ equipment configured as a closed system consisting of a single-circulation gas flow path, dust generated in the gas flow path is cooled with low-temperature water from a water supply source, and heated water obtained by heat exchange through the cooling is used. A boiler feed water preheating device in a CDQ facility, characterized in that the boiler feed water is supplied as boiler feed water to a water feed deaerator of the boiler. 2. The primary dust collector comprises a dust cooling pipe having a water-cooled jacket, and is configured to supply heated water obtained by heat exchange in the dust cooling pipe to the boiler water supply deaerator as boiler feed water. A boiler feed water preheating device in a CDQ facility as set forth in claim 1 of the utility model registration claim. 3. The primary dust collector comprises a dust cooling pipe having a water-cooled mantle, and the secondary dust collector comprises a dust cooling cyclone having a water-cooled mantle, and the dust cooling cyclone uses heated water obtained by heat exchange to Utility model registration claim 1, characterized in that the primary dust is cooled in a dust cooling pipe, and the heated water obtained by heat exchange is further supplied to the boiler feed water deaerator as boiler feed water. A boiler feed water preheating device in the CCQ equipment described in 2.
